.NET Core Docker Image for SPA Applications (5 answers)

Closed 2 years ago.

Is there a way in Visual Studio 2017 to automatically enable Docker support for an asp.net-core Angular project? The option is disabled when creating a new one. It is only available for Web Application (MVC).

I am able to Enable Docker support (Project->Add->Docker Support) for the angular project after I have created the project, but when I start the application I get an exception that node.js is not available.

System.AggregateException occurred HResult=0x80131500 Message=One or more errors occurred. (Failed to start Node process. To resolve this:.

[1] Ensure that Node.js is installed and can be found in one of the PATH directories. Current PATH enviroment variable is: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin Make sure the Node executable is in one of those directories, or update your PATH.

If it is not possible to create it automatically how can I manually get the Docker support enabled for my Angular project?

Answer 1

I solved my problem.

I needed to install nodejs also on my image, cause it is needed by webpack. I have changed my Dockerfile to also install nodejs version 6

FROM microsoft/aspnetcore:2.0
RUN apt-get update && \
    apt-get install -y wget && \
    apt-get install -y gnupg2 && \
    wget -qO- https://deb.nodesource.com/setup_6.x | bash - && \
    apt-get install -y build-essential nodejs
# Rest of Dockerfile

Using only RUN apt-get update && apt-get install -y nodejs was not enough, cause this installs version 4 of nodejs and it was installed in folder nodejs, so that the WebpackDevMiddleware did not find the node executable.
